Spatiotemporal detection of Kelvin waves in quantum turbulence simulations
Spatiotemporal detection of Kelvin waves in quantum turbulence simulations
We present evidence of Kelvin excitations in space-time resolved spectra of numerical simulations of quantum turbulence. Kelvin waves are transverse and circularly polarized waves that propagate along quantized vortices, for which the restitutive force is the tension of the vortex line, and which play an important role in theories of …
